feat(frank-dragoon): double the KV pool to 2 x ctx for slot parity

frank-dragoon's total in-flight context was HALF frank-zealot's: zealot runs
one 401,408-position pool split into two 200,704 conversations, while dragoon
ran ONE 200,704-position pool behind its two slots, so a single maximum-length
request filled it and two long conversations had to stay under ~100k each.

HALOGEN_KV_POOL_POSITIONS 200704 -> 401408 = slots x ctx, the top of the seam's
legal band (ctx <= pool <= slots * ctx). The PER-REQUEST ceiling does not move:
HALOGEN_CTX stays 200704, because the checkpoint's native window is 262,144 and
the engine's own 400 text refuses to exceed it without HALOGEN_ROPE_YARN. What
this buys is concurrency, not a longer conversation, which is why the harness
contextWindow (155648 = ceiling - 45056) is untouched.

Cost: ~10.8 GiB of KV where 200,704 cost 5.5 (262,144 cost 7.2; the
2026-10-06 shape's 524,288 measured 14.6), taken from the page cache the 51.2 GB
n-gram table reads through — the warm prompt-cache ratio is the number to
re-measure after the boot. Engine-side total goes 74.1 -> ~79.4 GiB of 121.2.

Also carries scripts/download-frank-zealot-bonsai2-ptq1.sh: the PTQ1_0 candidate
payload fetcher (5,946,648,928 B, LFS sha256-verified, mmproj hardlinked), with
the publisher's own throughput table in its header — the packing is smaller but
the card measures it SLOWER on Ampere, so the swap is decided on our card, not
on the card's A100 row.
